Specification of Letters Patent.

To all whom it may concern:

Be it known that we, HIDEsAKU HORIKAWA, KA'rsU'rAno SHIBATA, and TsUoHrrARo H1120. subjects of the Empire of Japan, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Cookers for Use on Boats; and we do declare the following t0 be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference bein had to the accompanying drawings, an to the characters of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in cookers adapted for use on boats, the object being to provide a stove-like structure so equipped that a removable pot, receptacle or vessel may be supported therein in such a manner that it will maintain its normal vertical position regardless of the tilting of the boat due to the action of the waves. A device of this character is more especially valuable during what is called rough weather on the water when the rocking motion of the boat is such that without some provision o f this character, it is impossible to cook food in a receptacle containing water, since the rolling of the boat will tilt the vessel suiiiciently to spill its contents or a relatively large portion thereof.

In our improvement, the fuel containing shell or stove-like structure is equipped with what are known as gimbals which consist of two movable hoops or rings, one within the other, the outer being capable of rotation about a fixed horizontal axis lying in its plane, and the inner capable of rotation about an axis lying in the planes of both rings and perpendicular thereto.

When the tilting of the stove or fuel re ceptacle is in a plane parallel with the axis of the outer ring, this ring alone together with the stove in which its pivots are mounted, are given the tilting movement, while the inner ring within which the cooking vessel is supported, maintains its horizontal. position while the cooking vessel maintains its vertical position. Again, when the vessel istilted in a plane formin angles with the axis of the inner ring, bot rings maintain their horizontal position or a position in which their axes are both in a horizontal plane, while the stove tilts to form any desired angle with such plane.

Having briefly outlined our improvement, we will proceed to describe the same in detail, reference being made to the accompanying drawing in which is illustrated un embodiment thereof. In this drawing:-

Figure l is a central vertical section taken through our improved cooker.

Fig. 2 is a fragmentary section taken on the same plane as in Fig. l, but showing the stove tilted in a plane parallel with the axis of the outer ring.

Fig. 3 is a similar view showing the stove tilted in a plane forming angles with the axes of both rings.

Fig. 4 is a view similar to Fig. 1, but islhowing a gasolene burner for supplying the eat.

Fig. 5 is a top plan view of the construction shown in Fig. 4, with the cooking vessel removed.

'Ihe same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the stove having an opening in its top carrying two opposltely disposed pins 6 which are fixed to the stove and upon the inner extremities of which is pivotally mounted a ring 'T which consists of the central segmentl of a sphere, this ring being curved to permit it to tilt to the position shown in Fig. 2 for instance, without interfering with an outwardly projecting circumferential flange 8 with which the cooking vessel 9 is equipped a short distance below the top thereof. Again, by reason of the curved or spherical structure of the ring 7, the stove member 5 may tilt to a considerable angle (see Fig. 3) without opening the stove at the top to any considerable extent, as will be readily understood by reference to the drawing.

Again, the spherical ring 7 is equipped with two inwardly projecting pins 10 upon whose inner extremities are plvotally mounted the inner ring 12 which fits closely around the cooking Vessel just below the fiange 8. As shown in the drawing, the axis of the two pins 10 is perpendicular to that of the two pins 6.
